Q. Select the outlier in the data set.5,42,44,48,49,52,54,60
Identify Outlier: Identify the data set and look for any number that appears to be significantly different from the rest of the numbers.Data set: 5,42,44,48,49,52,54,60Looking at the data set, we can see that the number 5 is much smaller than all the other numbers, which are all above 40.
Calculate Mean and Standard Deviation: To confirm the outlier, we can calculate the mean and standard deviation of the data set and see if the number 5 falls far outside the range of the other numbers.However, for this simple data set, it is clear without calculation that 5 is the outlier because it is significantly lower than all other values, which are relatively close to each other.
